where Fsampling
– frequency is set in "SETTINGS" (sampling frequency);
WF bandpass is set from 1 to 5000 Hz with a step of 1; 10; 100; 1000 Hz.
You can use the bandpass-function to adjust both the high pass and the low
pass. This is very helpful when you want to quickly determine the frequency
band for the best possible defect display - especially for rotor applications or
inspections of rotating parts.
Note
. Only one filter can be set in the frequency selected by an
operator. Activation of the other filter makes the earlier selected filter inactive
within the set frequency.
9. "
" - selection of the position of complex plane centre. Can be set
in the following positions:
- complex plane centre,
- in the right
centre of the screen,
- in the right upper corner,
- in the upper
centre of the screen,
- in the left upper corner,
- in the left
centre of the screen,
- in the left bottom corner,
- in the bottom
centre of the screen,
- in the right bottom corner,
- per-
channel display when operating in double frequency mode.
10. "
Grid"
– variants of marking for the complex plane: "
"
– square,
"
"
– radial, "
"
– Off.
11. "
Axis"
– activates coordinate axes.
12. "
ALARM"
– activation and setting of frames (threshold levels).
Types of frames:
- frames are switched off,
- circle frame type,
- threshold frame type,
- sector frame type,
- cut-off frame
type.
13. "SWEEP"
– number of samplings displayed on time charts (see
Figure 8, pos. 4) - 256; 512; 1024; 2048; 4096; 8192; 16384, 32768
measurements.
14. "PROBE"
– Connector type: "Refl", "Bridge", "Single".
15. "RPM"
– rounds per minute for the eddy current rotary scanner.
Selected from the standard range: 600, 840, 1020, 1200, 1500,
1800, 2100, 2400, 2700, 3000.
16. "ROT"
– type of connected rotary eddy current scanner SVR-02 or
MINI DRIVE.
17. "Mix type"
– is selected for the frequencies mixing (setting is
available in double frequency mode), where: "+"
– summation, "–" –
subtraction, "~X+" -
summation with inversion in Х-direction, "~Y+" -
summation with inversion in Y-direction.
